Abstract
Wheat is the major staple food crop and a major source of energy for Indian
population. India has achieved remarkable progress in wheat production during the last 4
decades and is continue to be second largest wheat producing nation in the world. The
wheat production has increased manifold from 6.60 million tonnes at the time of
independence to 107.18 million tonnes in during 2019-20. The present investigation
entitled “Performance of late sown wheat varieties under conventional and zero
tillage” was conducted in rabi season of 2019-20 at Research farm of College of
Agriculture, Banda University of Agriculture and Technology, Banda. The experiment was
laid out in Split plot Design with three replications. Tillage methods were taklen in main
plot (Zero tillage and conventional tillage) and five varieties ( HI1863, HI 1544, Shriram
bioseed 2001, Raj 4120 and K 1317) were taken in sub plots. Results revealed that
adoption of zero tillage has recorded maximum emergence count, plant height, dry matter
accumulation, tillers/m2
, root length CGR, and RGR, as compared to conventional method
of crop establishment. The 10.38 per cent grain yield advantage was recorded with zero
till wheat as compared to conventional method. Similarly, 8.2 per cent advantage was
recorded in straw yield of wheat as compared to conventional sown wheat.
Crop grown under zero till condition gave highest gross return of Rs.95799/ha, net
return of (Rs.60509) and B: C ratio (1.71) as against gross return (Rs. 87129/ha), net return
(Rs 48554) and B:C ratio (1.25) obtained from conventional sown wheat. Maximum and
minimum grain yield and straw yield were recorded with K 1317 and HI 1563,
respectively. But varieties did not influence significantly in relation to yield and harvest
index. Interaction effect between tillage methods and varieties were significant on
emergence count, plant height at maturity, tillers production, drymatter accumulation at 60
days stage, and root length at tillering stage, spike/m2
and grains/spike. But yield and
economics were not affected significantly. Therefore on the basis of results obtained,
sowing of wheat by zero till method and use of K1317 variety of wheat is best combination
to get higher yield and profitability.
